and useful Improvements inl Horological Apparatus, of which specification. Y

My invention relates to horological' apparatus 'andmore specifically to' a #device through the.. medium of which vthe time 'of any place upon the surface of the globe of known longitude may be determined with easevand expedition.

A `further object is apparatus as mentioned which willibe of simple4 construction Vand efficientin use.

Other objects will appear hereinafter. The invention consists inf-the combinations and arrangementsof lparts hereinafter described and claimed. f

The invention willr'be best-'understood by accompanying drawings whicht Y Figure 1 is a frontl elevation of `a"device embodying my invention, Fig. 2 is a top 3 isan enlarged deofFig. 2, the parts of the construction disclosed with the exception of the curtains, be-

4 except vat the terminal posts 1 project in both directions, that is `said arms are arranged in. pairs one of'which projects forwardly and the other rearwardly from the corresponding post. `The sections 44 of the arms of each pair are formed integral as clearly vshown ini'F ig. 6, rendering it possible to use butasingle set screw in. connectionwith each pair ofsaid armsl for fastening the same to the corresponding post .1.

At the outer ends of arms 4 are mounted two sets of rollers 7 andy 8, the rollers 7 be# ingy of'I the upper set of rollers and .the roll!l ers 8 :the lower set. Mountedfor travelv around said setsgofLrollers 7 and 8 .are end,-V less curtains orbeltsf9 and 10 respectively held in positionrby `means of studs v11- provided at the respective ends of said. rollers which are adapted to vengagecwith. perforations 12 provided adjacent the longitudinal edges of said curtains. rlhis provision also prevents slipping of the cur! tains upon said, rollersv as will be readily understood.v Y D The rollers 47 and 8 at the respective ends of the supporting frame are formed integral and a ratchet wheel 13 is provided at the point of connection of said rollers for .effecting rotation thereof. i Said ratchet wheel cooperatesv with a spring pressed pawl-14 carried'byfa manually operable oscillatory lever lwhereby through oscillatory actua'- tion oflsaid lever the ratchet wheel coperating therewith will be intermittentlyV rotated to reffectcoresponding feeding or movement ofthe belts 9 and 10. A lever 15 and cooperatingpawl and ratchet wheel 13 are provided at each endof the supporting frameso that feeding: of the belts. 9 and 10 maybe eifected from a position at either end of the device. Y f Y f f .Provided at the adjacent longitudinal edges side ofv the device is an lelongated strip 16l rigidly supported by means ofl supporting.- arms 17, the strip l'being so arranged that. during travel ofthe curtains 9 and 10, the inner longitudinaledges thereof will move inA close proximity with `the longitudinal' edges of saidstrip; c Y Y Y Providedupon the outersides of curtains 9 and 10-are spaced verticallyL extending` lines V18 indicative-of the Vgeographical degrees of longitude, the space between the adjacent lines corresponding to' fifteen degreeslicV ionginial as indicated by the f grad-unions coperating with said lines as clearly shown in Fig. 1. One of said lines 18 is designated the zero line of longitude-the lines at either side thereof being numbered correspondingly so that the endmost lines correspond with 180 degrees east and west longitude respeo` ocloc'k midnight to six oclock in the morning.; ANL-day referring to the hours'from six oclock inv the morning to twelve oclock non; P.

Alsofprovided uponthe outer sides of V.curtains 9 and 10 are spaced parallel hori- V zontal lines 19 which are indicative of the geographical lines of latitude.' Stationary strips 2O provided at the respective ends of the device and rigidly supported by the respective ends of strips 16 are graduated for coperation with i thezlinesl-Q. The arrangement is Vsuch as will 40 be seen, that the strip 16 is .positioned atta locationcorresponding with the equator, the lines 19 at either-side thereof-or above and below the samecorresponding with thefnorthv .south geographical latitudes andbeing and numbered to correspond so that'thev outermost lines 1-9` will -'be numbered 90 degrees corresponding withy the northv and south poles of thel earth.; .Y l' v iVith the arrangement set forth it will be Seen that'after thecurtains 9 and 10 have. been set so that theV line of longitude of the` place orv city in which the operator is lo-l `YcatedY is .in registration withthe proper hour of day shown uponV the strip 16, the time at any other place maybe readily and Y easily-found providing the longitude of the which willbeprinted ,thereon at points onr said ci'irtains-corresponding with the lati- 6 5 place'is known, the time of'any other place being that indicated by the hour graduation upon strip 16 registering with the longitude The curtains 9 and 10k "are ofsuchcsizeras to be adapted to accomline of that place.V
